Abstract
The sintering process can be defined as a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke) with the objective of obtaining a product with the suitable characteristics (thermal, mechanical, physical, and chemical) to be fed to the blast furnace. The sintering process is described in this chapter, where the main reactions are presented, as they indicate the different phases that can be found in a sintered product. Several of the indices that are used to define the quality of the sinter are described in this chapter: Tumbler index, Reduction Degradation Index (RDI), and reducibility test. The chapter is complemented with solved exercises and problems.
